Environment
Release : 6.6, 6.7
Component : CA RELEASE AUTOMATION CORE
Cause
During analysis of the issue we observed that the dependency jar related with this action pack is not downloaded and installed along with action pack install via ROC.
Resolution
Please find instruction below to resolve the issue.
1: On the NAC server create a backup/zip of actionslib directory
2: Download the dependency.zip either from Action Packs FTP site
3: Extract the zip on the computer from where you can access the ROC UI
4: Go to ROC UI -> Administration -> Action Management -> Import and import all the jars from extracted directory(in step 3)
5: Try to run the action again and validate, the error should not be visible any more with dependency jars available.
